What is the size of the photo for a driver's license?

Driver's license photos must be one-inch white background photos. According to the regulations on the application and use of motor vehicle driver's licenses, the size and color of the photos have been clearly specified. The requirements include a front-facing, single-person, half-body ID photo of the applicant taken within the last six months, with a white background and clear visibility of the person. Nowadays, driver's license photos can be retouched, but the degree of retouching should not be excessive. According to the regulations, the image should be clear, with rich layers, natural facial expressions, and no obvious distortion or stretching. Photos that meet these requirements can be used. When applying for a motor vehicle driver's license, six photos need to be submitted. According to the motor vehicle driver's license file management, the resolution of the photos should be 300dpi. However, requirements may vary slightly by region. Specific requirements should be based on local policies, and photos can be taken directly at the driving school during registration. Holders of A1, A2, A3, B1, or B2 driver's licenses must report to the traffic management department of the public security authority within thirty days after the end of each scoring cycle for verification. However, if there are no demerit points recorded during a scoring cycle, the verification for that cycle is exempted.

What Causes Brake Disc Noise While Driving?

The causes of brake disc noise while driving include normal ABS activation, rust on brake pads/discs, excessive wear of brake discs and pads, and installation issues. Below are detailed explanations for each cause: The ABS operation process is actually a cycle of locking, releasing, locking, and releasing, keeping the vehicle in a state of near-lock rolling. Therefore, when ABS is activated by sudden braking, noise is normal, and pressing the brake pedal fully can resolve it. After prolonged parking, especially in humid weather or after rain, some rust or dirt may form on the brake discs or pads. Driving for a while can solve this, or applying butter or specialized lubricant at the connection between the brake pads and calipers may help. Both brake discs and pads are high-wear components. Every time you brake, these two parts experience friction, leading to wear over time. Excessive wear naturally causes noise, so regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 km, while brake discs last 100,000-120,000 km. Incorrect installation or mismatched models of brake pads can also cause noise. Reinstalling the brake pads may resolve this. Owners should have brake pads installed at professional auto repair shops, especially those who have had them replaced at roadside stalls, as extra caution is needed.

Where to Check the Mileage of a Car?

Car mileage can be viewed on the odometer, usually indicated by ODO, with the unit km following the numerical value, representing the total distance the car has traveled. Its function is to inform the driver of the distance covered, allowing for fuel cost calculations and indirectly reflecting the car's fuel efficiency. The car odometer also includes two LCD digital display windows connected to the same signal source, respectively accumulating the current trip mileage and the total mileage. The current trip mileage typically has four digits and can be reset for short-term counting, while the total mileage has six digits and cannot be reset. Generally, there are two types of car mileage: one is the total mileage the vehicle has traveled, and the other is the measurable mileage. The measurable mileage can be manually reset by the owner, usually with a small button (cylindrical) next to the number; pressing and holding it will reset the value. ODO is the abbreviation of the English word 'odograph,' representing the total mileage. TRIP stands for short-distance mileage, also known as the trip mileage, which is convenient for users to calculate the distance of each trip. The trip mileage can be reset by pressing and holding the clear button. It can also be used to calculate fuel consumption. The method to calculate the fuel consumption per 100 kilometers is to fill up the tank, reset TRIPA or TRIPB, drive 100 kilometers, and then fill up the tank again. The amount of fuel added represents the fuel consumption per 100 kilometers.

What Lights Should Be Turned On When Driving in Heavy Rain?

When driving in heavy rain, turn on the fog lights. Only use the rear fog lights when the rain is extremely heavy. Fog lights emit a particularly penetrating beam that can not only illuminate the road ahead over a longer distance in rainy or foggy conditions, but also enhance visibility, making your vehicle more noticeable to others from a greater distance. Use the parking lights in light rain: The use of lights is crucial when driving in the rain. At the onset of rain when the sky gradually darkens but visibility remains relatively good, you should use the parking lights. Turn on the headlights or fog lights in heavy rain: In heavier rain where visibility is low, the rain itself can obstruct your view. Using headlights or fog lights can improve your visibility of the traffic conditions ahead. Additionally, in foggy conditions or when the side mirrors of the car are obscured by water, the clarity of the view can be reduced. If the vehicle behind you has its fog lights on, your car will be more easily noticed in the mirrors, thus enhancing safety. Do not use hazard lights while driving: Hazard lights are meant for emergency situations only. They should be used in very dangerous circumstances, such as when parking on the roadside, experiencing vehicle malfunctions or being involved in a traffic accident on urban roads, when towing a malfunctioning vehicle (both the towing vehicle and the towed vehicle should turn on the hazard lights), or when driving on highways in low-visibility weather conditions like fog, rain, snow, sandstorms, or hail with visibility below 100 meters.
